The two-time Pro Bowl tackle was acquired in February from the Dolphins for a seventh round pick, with Jacksonville sending tight end Julius Thomas to Miami in a separate trade. Before coming to Jacksonville, Albert played six seasons for the Chiefs and three seasons from the Dolphins.

According to NFL.com’s Ian Rapoport, the decision to retire could cost Albert a decent amount of money.

Marrone will be looking for Bortles to take a step forward in his fourth season in the NFL. In his prior three seasons, Bortles has never completed more than 60 percent of his passes. He’s also never thrown less 16 interceptions in a season. However, in 2015, Bortles did throw for over 4,400 yards and 38 touchdowns, and those are numbers the Jaguars’ coaching staff hopes their quarterback can replicate this season.

The Jaguars kick off their preseason on August 10 when they travel to Foxborough to take on the defending champion Patriots.
